Overview of JSS3

In 2020, JAXA would start operation of new supercomputer system called JSS3 which is the successor of JSS2.

Computational fluid dynamics (CFD), which has been developed together with the supercomputer, has evolved from research and development to the essential, practical role of the various areas. Use of the supercomputer has been expanded to other fields, such as the processing of earth observation data or an AI platform.
JSS3 is aimed to support the followings.

  1. Infrastructure of Numerical Simulations to empower our international competitiveness in the aerospace
  2. Data Center as a large-scale data analysis platform
  3. Research and Development Platform for acceptance of emerging needs

JSS3 consists of TOKI as the computing infrastructure, and J-SPACE, the archiving infrastructure.
The name TOKI comes from the name of Japanese bird toki (crested ibis (Nipponia nippon)), Japanese expression of “time and space” and “solution”. TOKI also expresses “TOkyo and ibaraKI”, where JSS3 is located.
Major components of TOKI are, TOKI-SORA, TOKI-RURI and TOKI-FS.
